DOOR.

SPECIFICATION forming part f Letters Patent No. 544,985, dated August20, 1895. Application iilecl December 4, 1894.' Serial No. 5 30,773. (Nomodel.)

To all whom t may concern: l

Be it known that I, WILLIAM E. KELLY, of New Brunswick, in the county ofMiddlesex and State of New Jersey, have invented a certain new anduseful Improvement in Doors, of which the following is a specification.

I will describe a door embodying my improvement, and then point out thenovel features in claims.

In the accompanying drawings, Figure l is a vertical section takentransversely through one of the walls of the masonry of a generator, theplane of the section being the center of a doorway and the door and anumber of water-tubes being shown in section. Fig. 2 is a horizontalsection of the said wall, doorway, and door, some of the water-tubesbeing indicated in horizontal plan. The door is also shown in this gnrein dotted outline, but in a different position.

Similar letters of reference designate corre-` sponding parts in allfigures.

Referring to the drawings, A indicates a' doorway or opening in the wallB. As shown, the vertical sides of the doorway incline toward each otherin the direction of the inner side of the wall in which it is formed, s0

that the opening is made to taper transversely toward the tubes. This isan ordinary form and is advantageous because it affords great freedom ofmovement for a brush or nozzle with an opening comparatively small atthe inner side of the wall B. There may be any number of these doorwaysor openings. In each doorway or opening A a facing-plate O may bearranged, and this may be made as a casting. It conforms to the shape ofthe openingor doorway and extends to the inner side of the wall in whichsuch doorway is formed.

D designates a door hinged to the facingplate C on that side which isoutermost, and secured by a locking device CZ when closed.

E designates a stopper for closing the opening in the facing-piece closeto the inner side of the wall. As shown, this stopper consists of a barcapable of filling the space between the sides of inner side of the walland connected by any desired number of arms c with the inner side of thedoor D, they being pivoted to the door or some appartenance of thelatter. In the present instance these arms arev pivotally connected bybolts F with lugs formed upon the door.

It is obvious that when the door D is opened the stopper may be swunginto any desired position out of the way, and that before the door isclosed the stopper will be swung into the proper position to slide alongone of the sides of the facing-piece, and that after it has beenadjusted into this position the closing of the door will close thestopper.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination with a door for a door'- Way tapering from one sideto the other, of a stopper pivotally connected to the door and servingto close the contracted portion of the doorway, substantially asspecified.

2. The combination with a door D, for a doorway tapering from one sideto the other, of a stopper E provided with arms e pivotally connected tothe inner side of the door, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
